Introduction:

This document describes an
ontology for publishing Linked Open Data (LOD) in the Open Data Web.The initial
ontology is being designed for implementing CC licensed data in the Union Catalog of Digital Archives Taiwan . However, the core model of the
ontology is flexible and adaptable for other uses in curating, publishing and
reusing their data according to users’ context..

Status:

The ontology is in its draft stage and calls for comments and suggestions.
The implementation of using voc4odw is at data.odw.tw.

Overview:

The ontology
consists three parts, namely the Core Model, the Collection IDs and the
Vocabulary from external.

oskos:definition "A main concept to relate people,
place and time. An event resource can be a statement about human-associated
process like birth without spatio-temporal
descriptions or a spatial entity like an unknown event locate in some place or
an unknown event as a temporal entity with time descriptions."
.

###voc:KnownEvent

ordfs:subClassOfdata:Refined

oskos:definition "Event concept is being recognized
from specific field description of the primary data. For instance, data of the
photo taken in a photo event, place of the object created in a creation event,
or people who are involved in a specific event." .

###voc:Object

ordfs:subClassOf :ConceptualModel

oskos:definition "voc:Objects
are groups of SKOS concepts for event's factors and products." .

###voc:OpenData

ordfs:subClassOf :CoreModels

oskos:definition "Data curated and published in
response to the global demands on public access to data. For high-level
requirements of reproducibility, the component and mechanism design are in the
packaging of articles, data and code." .

###voc:People

ordfs:subClassOfvoc:Event

oskos:definition "A concept to combine agent, person,
organization and project. An event resource can be a statement about
human-associated process like birth without spatio-temporal
description." .

resource. Semantic meanings of different interpretations are provided from
conceptual model. Different interpretations or different derivation processes
are curated in different refined versions (ex. r1, r2, r3...). " .
